This inventionrelatesto a roadoiler, and par ticularly to'theconstructionianda mountingiof the spray bar which extends transverselyofthe supporting vehicle and the road; and fromwhi-chfl the oilisdistributed onto the latter. s 4 I The principal, objects of myinvention areto providea spray bar unit so mounted that'it may beadjusted laterally a well as vertically oftthe supporting vehicle; onehaving ganoperators platform mounted on and adjustableswith the unit;and one having horizontally.foldabie end portions.

By reason'of the features above'generally defined, shoulders or otherlaterally offset areas may be readily oiled without the vehicle alsoriding the shoulders; then-operator ishin position to seeand control theoiling; operation as it'takes control valves Idepen'd from pipes -I and{the place; and the overall width of the spray bar may be quicklyreduced for transportation. and

the like. v v ;j .7: .s .7 The device may be used for emulsion as well Afurther object of the invention sltofprodiiee a simple and inexpensive;device and yetvv'one which will be exceedingly efiectivefor thegpur poseforwhi'ch it is designed; 1 ,j v

The spray bar is shifted laterally of; its sup-' porting structure, andindependentlyof its; raising and lowering, by the following a means:

Mounted on top of andgextending lengthwise of pipe I is a rack; 22.

The hand wheel and crank handle are laterally offset so asnot to interfere with each other. Shafts 26 and 24 areconnected indriving relatio within housing by gearing 28.

: In order to hold the foldable pipe sections 2 either in extended orfolded positions, the following arrangement is provided: Secured on andprojecting forwardly from pipe I adjacent its ends are brackets 29having lateral outwardly projecting saddle extensions 30 at theirforward end adapted to engage over one-half of pipes 2 claim as new anduseful and desire to secure by LettersPatent is: i

1.

when the latter are folded back so -as to 'be at i right angles to pipeI, as shown-in Fig. 1. 7 Each pipeZ carries an upstanding stud 3ladaptedto engagein a horizontal slot 32 in the corresponding saddle extension30 when said pipe 2 is folded;

In orderxto support an operator from'theispray bar unit, rearward-1y.extending brackets" 38 are mounted onlpipe [in widely spaced relation.-As.

In this manner, thelevelofthe platform is below that of 'the'upper end of levers 0 so thatthe latteryare 'exposed aboveiand infront of, the feet of'theoperator,-which may thus be usedt'o manipulate the valves. A han'd raillimit 38 is mounted in connection withthe platform for .theconvenience'of the operator. g Q From the foregoing description it will be readilyseen that I-have produced such a device'as substantially fulfills theobjects'of the invention as set forth herein: 1
